Yes, look at whether root canals may be an option.
Kris has 1 tooth left to go, then all his teeth will have been root Canalled . We chose this over extraction and particularly HBO. Neither of us were keen to do HBO at this stage. Really feel that we want Kris to be some years down the track before risking growth of any stray Ca cells left - if any.
Fortunately our public health system has done all this work for Kris.
